Useless Add simple UV's

When you do texture painting then you may get a warning about missing UV's. You can add some simple UV's. Which are useless for texture painting since they overlap. Which makes this feature more or less useless.

A better method would be to add Smart UV Project here. It is not perfect, but non overlapping. Maybe we find a way to add Smart UV Project here instead of this useless and odd cubic projection.

It's our fix for cubic mapping that strikes back here. Without my changes the cubic mapping is fubar, and goes into the negative UV areas. With the changes the mapping for add simple UV's is fubar, and produces overlapping geometry.

Let's have a look if we can have both ...

The normal UV methods are no go here. We can get Smart Project and Lightmap method to work. But the Last operator stays open. And the warning doesn't vanish. This part is C code.

Fixed in master

We have two classes here now. The one is the old cubic mapping from Blender. It creates non overlapping mapping with add simple uv's. The other is the six sided cubic mapping that maps the cube really from six sides, and stays within the uv space of o to 1.

Okay. Blender devs have meanwhile also fixed this issue. In a more elegant way. And this means we have to remove our code again.

This will most probably happen in the Sync Blender Master branch, and go into the master with the next version then.
